1)
Emergency Off (EMO) button
- An Emergency Off (EMO) button located on the
front of the unit (and remotely if option is selected) is utilized by the user in the event
of an emergency condition to shut power to the unit (and other devices if option is
selected). It is a SEMI S2 compliant device with a direct opening action mechanism,
and safe break action.
2)
Door Interlock Switch
- A door interlock switch mounted to the front cabinet door
is used to indicate if the door is open or closed. If the front door is open, the power
will be cut to the unit. This safety device features force guided contacts and a
tamper resistant mechanism.
3)
Safety Relay
– The Safety Relay monitors both the Emergency Off button and the
Door Interlock Switch. The Safety Relay incorporates redundant relays in
conjunction with the emergency off button switch and the safety open-door interlock
to achieve safety category 3. The Safety Relay determines whether or not to
provide power to the unit.
4)
Ground Fault Circuit Interrupter (GFCI)
– The Ground Fault Circuit Interrupter
(GFCI) monitors the heater amperage and any circuits containing 120 volts or more
if a suspicious current leak is detected in the circuitry.
5)
Thermal Cut-Off Sensor
– The thermal cut-off sensor is a thermal sensor which
opens once it’s breaking temperature is exceeded. It is used to shut down the
heater when a runaway heating condition occurs.
6)
Safety PLC (Programmable Logic Controller)
- Safety PLC monitors the high
limit thermocouples, the GFCI and Thermal Cut-off Sensor status using redundant
force guided relays, and controls the Heater Master Relay (which controls the
heater contactor) and the Heater Safety Relay (which controls the SCR output
signals to the heater).
7)
Water Leak Deluxe (Optional)
– The water leak deluxe option consists of
monitoring for system leaks via water leak sensor and isolation valves which shut
off the incoming process fluid and the heaters as well. This option allows the user
to isolate and reduce a pressurized system to a zero-energy state prior to
maintenance or service work. The system uses two pneumatically or manually
operated 2/2-way diaphragm valves to isolate the system. The valves are
located at the input and output. (Optional).
8)
Lockout/Tagout (Optional)
- Lockout/Tagout is optional for the Aquarius D.I.
Water Heating System. This provides a fusible disconnect switch on the unit
and conforms to SEMI S2-0715 to isolate the unit electrically for maintenance
and service work. The handle is lockable. If the lockout/tagout option is not
included, the main disconnect is customer supplied. (Optional)
